Originally, it calls xmalloc to set index in ioapic_rte_to_remap_entry(). When make with debug=y, it may trigger spinlock BUG_ON because allocate memory with interrupt disabled. This patch doesn't allocate list_head entry in ioapic_rte_to_remap_entry(), instead allocate the array in enable_intremap() to avoid allocating memory with interrupt disabled.
